Errr, that doesn't look natural. Try restarting the page

Thank uuuuuuuuuuuuu

8 (c+3)      Substitute c=9

8(9+3)

8(12)

96

i feel like a skeleton right now I'm tired to the BONE and i still have a skeleTON of work to have done (sorry for all of the bad puns)

Just dandy...in fact I feel like I could take on the whole world...or a whole forum. Jk haha ;)

Just look at the line of the graph.....where is it positive (above the x-axis)?

from -3 to 1   and from 4 to infinity   (not inclusive....that means it is ZERO at -3 1 and 4 so those numbers are not included))

(-3,1)   and  (4, inf )     

Rate that coffee is being added to the urn  after 4 hours is  3(4)^3 + 20   = 212 cups/hr

Rate that coffee is being dispensed  from the urn after 4 hours = 5(4)^2 + 10  =   90 cups/hr

So

(e - l)(4)   =   212 - 90   =  122  [ this means that  after 4 hours, coffee is being added to the urn at 122 cups / hr ]

This is a cosine wave with amplitude 0.75 and the usual 2pi period

= .75 cos x

Sorry....looked at wrong info:

The amplitude is 1/2 of the height of the sinusoidal wave form   (or the height from the midline of the wave)

this wave goes from    2.5 to -2.5      amplitude is 2.5 

well that was simple

Thanks CPhil, your amazing :)

It means that they are online....

If you scroll down, synth....yours is bolded, too....

No sinister motives.....LOL!!!

no prob

it means they are on this site

4 (7 + 5)   =  4(12)   =  48

The only statement that we can definitively say is true is the third one

f(-2)  = 2

g(-2)   = 1

So

f(-2) > g(-2)

Okay thanks

It's  called "Desmos"......easy to use.......and free on the web

4 + 7x -2  isnt equivalent

Yea I posted this before you replied. I thought if I reposted you would see it faster.

Hey is that like a website for graphs?
